Dear Sir，
Thank you for invite me to the summer English course in your school. As for your choice between the two courses, I prefer the four-week course because of this will allow me more time to do some traveling but make a few new friends. Of all the subject I’m learning at school, I like English best. I had been learning English for eleven years but my spoken English remains poorly. So I really hope to take this chance improve it. If possible, I’d like to stay with a family for a couple of days in order that I can know some customs in England, that I’m particularly interested in. I believe I will have wonderful time this summer.
Yours truly,
Li Hua
As a boy grown up in India, I had longed to traveling abroad. I used to listen to the stories my father told me about her stay in Canada and trips to Europe in 1970s. My big moment finally come in the summer of 1998 when I was able to accompany my parents to Europe, where my father was to attend for a meeting. The service during the flight to Frankfurt was such nice that even today I can still remember them. The flight was really smooth and thorough enjoyable, even for someone as me, who is otherwise scared of flying.
On January 5th, students in our school visited Robot World, which we saw a great diversity of robot. It was amazed to find those robots could do a great number of things just like real people, including playing chess, playing piano and drawing pictures. What’s more, the robots were in different kinds and shapes, which made us enjoyable. In addition, that excited me most was the show given by a group of robots. They danced just as if they are dancers on the stage. By visiting Robot World, I have learned a lot of about robots , especial about their functions and shapes. The great human wisdom is so powerful that it make us feel more comfortable live in the world.

I’m glad to write to you. It is near a month since you had left our hospital. I’m still worried about you. How are you get along these days? I think you may be much better now, but I’d better have a good rest and take good care of yourselves since you are sixty-year-old man. I still remember those days which you helped me to my English. With your help, I make good progress. But to my regret, my English remains very poor through I have made good use of my time. Can you give me some advice on it?

Dear Dad,
I know you were very busy with work, but I'm hoping if you can help me out anyway. I’m thinking of leave the football team, and I need your opinion. My homework this year is crazy, but I need more time to get them done.Since I’m the man of the house while you’re gone, I have much housework, either. On the other hands, I’ve put in two years on the team, and the coach says I’ll make captain soon. However, I’d like try something new. I’ve been thinking about photography, actual, and I want to meet some new kids. How do you think, Dad? I can’t wait to see you!
Yours,
Xiao Liang
